"I've always been a big fan of Rosario Dawson," the star mused at first. "Oh, you know what? I would have Marisa Tomei play me. I am such a Marisa Tomei fan," the "Born This Way" chanteuse said of Tomei, 46, who won an Academy Award for playing a wise-cracking "guidette" in 1992's My Cousin Vinny and has kept busy with high-profile movie roles ever since.

"All my friends call me Marisa when I get angry," Gaga explained. "Because my New York accent just flies out of my body and I start smacking my gum."

As for Gaga one day becoming a movie actress herself, it's definitely a possibility, she said. "I think at some point, yes," she said. "I think I'm sort of destined for that screen at some point."

The superstar also dished on her fitness routine during her Morning Mash Up chat. Her secret to staying skinny? "I am on the drunk diet," she quipped. "I live my life as I want to, and creatively. I like to drink whiskey and stuff while I am working."

But seriously, she explained: "The deal is I've got to work out every day, and I work out hung over if I am hung over. And it's about the cross-training and keeping yourself inspired. I have to say, I do a ton of yoga."

On Valentine's Day -- the day after she perplexed fans with her egg-y entrance at the Grammys -- Gaga spent the romantic day with some very special friends.

"I was in my bed with tons of shoes," she said. "I was holding all my shoes, my Valentines."
